We can use the product-to-sum formulas, which express products of trigonometric functions as sums. Let's investigate the cosine identity first and then the sine identity. Expressing Products as Sums for Cosine. We can derive the product-to-sum formula from the sum and difference identities for cosine. If we add the two equations, we get:High School Math Solutions - Trigonometry Calculator, Trig Identities. In a previous post, we talked about trig simplification.

Spinning The Unit Circle (Evaluating Trig Functions ) ...The Euler formula, sometimes also called the Euler identity (e.g., Trott 2004, p. 174), states e^(ix)=cosx+isinx, (1) where i is the imaginary unit. Note that Euler's polyhedral formula is sometimes also called the Euler formula, as is the Euler curvature formula. The equivalent expression ix=ln(cosx+isinx) (2) had previously been published by Cotes (1714).Identities Proving Identities Trig Equations Trig Inequalities Evaluate Functions Simplify Statistics Arithmetic Mean Geometric Mean Quadratic Mean Median Mode Order Minimum Maximum Probability Mid-Range Range Standard Deviation Variance Lower Quartile Upper Quartile Interquartile Range Midhinge Standard Normal Distribution

Here, we'd like to do the same, but instead of multiplying the angle by two, we'll divide it.In fact, the main tool to find the sin, cos, and tan half-angle formulas are the power reducing identities.Example \(\PageIndex{2}\): (Solving an Equation with a Double Angle Identity) Consider the equation \[\sin(2\theta) = \sin(\theta)\] The fact that the two trigonometric functions have different periods makes this equation a little more difficult. We can use the Double Angle Identity for the sine to rewrite the equation as
